Application led 1)ecembe1 26, 1923. Serial No. 682,741.

'To all whom t may concern.:

Be it known that I, Jamas J. Wil-Lern# citizen of the United States, 'and a resident of the city ot New York, borough of Brooklyn, inthe county of Kings and State of i As a further object the invention contem plates an attachment for a gasl hose which serves to loc-k the valve in a closed position against accidental or casual movement to an op'enposition, and which further functions to prevent a small child from manipulating the valve to open the same. A y

AS a still further object the invention aims to provide an attachment ot the character set forth which is comparatively simple in its construction, inexpensive to manufact-ure, which may be readily installed, and which is highly etlicient in its purpose.

lith the above recited and other objects in view, the invention resides in the novel construction set forth in the following speciication, particularly pointed out in the appended claims and illustrated in the accompanyino' drawings, it being understood that the rightis reserved to embodiments other than those actually illustrated herein to the iull extent indicated by the general mean ing of the terms in which the claims are expressed.

ln the drawings- Figure 1 is a side view ot the device in applied position, parts being` broken away and shown in section.

F ig. 2 is a plan view thereof'.

Referring to the drawings by characters of reference, A designates an outlet nozzle provided with a. controlling valve B having the usual valve core C and manipulating key D. The nozzle A is adapted to receive thereover the end E of a gas hose F.

The attachment constituting the invention consists oi a member 10 which is rigidly secured to the hose end E and a member 11 which is engaged with the key D ot the valve core and has pivotally attached thereto a rack bar 12 which is interengageably associated with the member l() coupling` the key and hose together whereby when the valve 'is in closed position the same is locked against accidental or casual movement to open position and'whereby said device urther functions as a mea-ns when the valve is open to close the same in event of accidental disconnection ot the hose end lll from `the outlet nozzle A. The specific means employedconsists in providing the member 10 4 with a split sleeve 13 which embraces the hose end and is clampedtheretoby a bolt 111 pass ing through the outturned apertured ears 15 of the sleeve v13. The member 1() is further provided' with a substantiallyv U-shaped arm 16 preferably formed integral witlrthe sleeve 13 and which is provided at its bight portion with a vertical slotI 17. The member 11 includes the key embracing portion 18 which is provided with a laterally projectm'g or horizontal arm 19 to which one extremity of the rack bar l2 is pivoted as at 20. The rack bar is provided on its under edge with a series of notches 21 defining teeth which engage with the lower edge oi' the slot 17 to couple the rack bar with the arm 1G. In'order to prevent accidental'up ward swinging movement and disengagement olf the notches 21 with the lower edge of the slot 17, a keeper pawl 22 is pivoted as at 23 within the upper end of the arm 16 and is engageable at its lower free end with the ratchet teeth 24E formed on the upper edge of the rack bar 12.

In use and operation when it is desired to lock the key D to hold the valve in a closed posit-ion, the pawl is swung upwardly to disengage the same from the ratchet teeth 2a. The rack bar 12 is then lifted to disengage the notches 21 from the lower edge of the slot 17 and the key is turned to close the valve. With the key in this position AAthe corresponding notch 21 is re-engaged with the lower end oi the slot 17 and the pawl 22 is swung to engaging posit-ion with the ratchet teeth 21. This etfectually locks the key and valve against accidental movement and prevents a small child from manipulating the key due to the complexity of the locking means. When it is desired to open the valve the lockingpawl 22 is manipulated to disengage the same from the ratchet teeth 2i, the rack bar 12 is lifted to disenga-ge the notch 21 from the lower end of the slot 17, the key is turned to open the valve, and the V n'ection of the end E of the gas hose from the nozzle A' Whichis 'only accomplishedby movement of the same in a direction axially of Vthejnozzl'e A, the rack bar 12 will exert 'aV pull onthearm 19 Vwhich Will rota-te the ltjey 'and valve to move the valve to its closed position. f f

I claim: Y

v1.,'lhe combination with a valved outlet nozzle and a hose connected thereto, of 'means of 'connection between the hose and the valve for respectively closing the valve when opened, in event of'disconnection of the Those 'from the outlet nozzle, and for 'locking the valve in closed position against accidental yopening movement of the same,

- said Ymeans comprising a member rigidly secured to the'hose, a memberengaged `with the valve, and interengageable adjustable Q. The combination with a valvecl outlet nozzle-and a hose connected thereto, of

Y meanso'f connection between the hose and locking the valve in closed position against accidental opening movement of the same, said means comprising a member rigidly secured to the hose and having a slot therein, a member engaged with the valve and having a radial arm, a rack bar pivotally connected to the radial arm and extending through the slotted portion with the teeth thereof engaging one end of the slot, and means for locking the teeth in engaged relation to said end of the slot.

3. The combination with a valved outlet nozzle and a hose connected thereto, of means of connection between the hose and the valve for respectively closing the valve when opened, in event of disconnection of the hose from the outlet nozzle, and for locking the valve in closed position against accident-al opening movement of the same, said meanscomprising a member rigidly secured to the hose and having a slot therein, a member engaged with the valve and having a radial arm, a rack bar pivotally connected to the radial arm and extending through the slotted portion with the teeth thereof engaging one end of the slot, said rack bar having a `setvof ratchet teeth, and

a locking pa'ivl carried by the member secured to the hose for engaging said ratchet teeth to retain thel rack in engaged relation to the end ofthe slot.
